The loud one. Spark rates this STEP 3 build at 106 decibels, four above the Force Evo version, and that single figure decides more about whether it suits you than anything else on this page.
Key Features
- Full titanium racing system for the Yamaha R6 and YZF-R6 Race.
- Titanium collector with Konix Evo silencer.
- Rated by Spark at 106 dB.
- STEP 3, connections machined from solid by CNC.
- 4.0 kg against 10.3 kg for the standard system.
- Racing part, not approved for road use.
Read the 106 First
Most European circuits publish a static limit and most of them land at 102 dB. A system rated 106 does not get through that test, and no amount of arguing at the gate changes it.
So this build makes sense in two situations: events with a higher limit or none at all, and machines that will run a dB killer for scrutineering. If neither describes your season, the Force Evo build GYA8873T is the one Spark rates at 102, and it costs the same money.
The Konix Evo Wedge
Where the Force Evo is ribbed and tapered, the Konix Evo is a wedge — narrower at the inlet, opening towards the outlet, with flat angled flanks instead of a round barrel. Spark finishes the EVO cases with a racing-style carbon end cap.
It is the cleanest-looking of the three shapes Spark offers for this motorcycle, and on an R6 tail that matters more than it does on a naked bike, because the case sits in plain view under the seat unit.
Two Hundred Grams Under the Force Evo
4.0 kg against 4.2 for the Force Evo and 3.4 for the Grid-O. The three sit close enough together that weight is not what separates them — the noise rating and the shape are. All three take just over six kilos out of the motorcycle.
What STEP 3 Refers To
Spark's third and current kit level for the R6, developed for engines in Supersport configuration and built with connections machined from solid on a CNC rather than fabricated. Those joints are why the collector can be split and reassembled repeatedly without the couplings going slack — which matters on a bike that gets stripped between rounds.
One practical note: a removable dB killer changes the measured figure, and plenty of riders run one for the noise test and take it out afterwards. Whether that is permitted is the organiser's call, not ours, and it varies more than you would expect between clubs.
Installation
Full system: the standard collector comes off and Spark's replaces it entirely. The STEP 3 connections are machined from solid on a CNC, which is what makes the collector joints repeatable when the system is taken apart between sessions.
